1.2 Safety / Proper Usage

Caution!

Note the torque tester’s capacity before use and ensure that the capacity is not exceeded.

Producing a torque greater than 150% of the tester’s capacity can damage the internal sensor. An

overload can occur whether the tester is powered on or off.

The tester is designed for various torque testing applications. Items that should not be used with the

tester include potentially flammable substances or products, items that can shatter in an unsafe manner,

and any other components that can present an exceedingly hazardous situation when acted upon by a

load.

The following safety checks and procedures should be performed before and during operation:

1. Never operate the tester if there is any visible damage to the AC adapter or the tester itself.

2. Ensure that the tester is kept away from water or any other electrically conductive liquids at all

times.

3. The tester should be serviced by a trained technician only. AC power must be disconnected and

the tester must be powered off before the housing is opened.

4. Always consider the characteristics of the sample being tested before initiating a test. A risk

assessment should be carried out beforehand to ensure that all safety measures have been

addressed and implemented.

5. Wear eye and face protection when testing, especially when testing brittle samples that have the

potential to shatter under force. Be aware of the dangers posed by potential energy that can

accumulate in the sample during testing. Extra bodily protection should be worn if a destructive

failure of a test sample is possible.

6. In certain applications, such as the testing of brittle samples that can shatter, or other applications

that could lead to a hazardous situation, it is strongly recommended that a machine guarding

system be employed to protect the operator and others in the vicinity from shards or debris.

7. When the tester is not in use, ensure that the power is turned off.

Series TT05 Digital Torque Testers User’s Guide

2 POWER

The TT05 is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these

batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period

of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the

receptacle on the tester (refer to the illustration below). The battery will fully charge in approximately 8

hours.

Caution!

Do not use chargers or batteries other than supplied or instrument damage may occur.

If the AC adapter is plugged in, an icon appears in the lower left corner of the display, as follows:

If the AC adapter is not plugged in, battery power drainage is denoted in a five-step process:

1. When battery life is greater than 75%, the following indicator is present:

2. When battery life is between 50% and 75%, the following indicator is present:

3. When battery life is between 25% and 50%, the following indicator is present:

4. When battery life is less than 25%, the following indicator is present:

5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.

Several minutes after (timing depends on usage and whether the backlight is turned on or

off), a message appears, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone

audio indicator will sound and the tester will power off.

The tester can be configured to automatically power off following a period of inactivity. Refer to the Other

Settings section for details. If battery replacement is necessary, the battery may be accessed by

removing the cover attached to the underside of the base.

3 SETUP

3.1 Mechanical Setup

The matrix of threaded holes in the loading table allows for the mounting of specialized fixtures, as

required for the application. When designing and mounting the fixture, ensure that the axis of torque

aligns with the center of the loading table. Side loading or off-center loading may produce erroneous

readings, and can damage the instrument. The tester can be mounted to a bench via four threaded holes

located on the underside of the base.

3.2 Installing the USB driver

If communicating via USB, install the USB driver provided on the Resource CD. Installation instructions

may also be found on the CD or may be downloaded from www.mark-10.com

Caution!

Install the USB driver before physically connecting the tester to a PC with the USB cable.

Further instructions for configuring and using the tester’s outputs are provided in the Communications

and Outputs section.

The tester will always power on with the unit selected in this sub-menu.

7 DIGITAL FILTERS

Digital filters are provided to help smooth out the readings in situations where there is mechanical

interference in the work area or test sample. These filters utilize the moving average technique in which

consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer

contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection

of 1 will disable the filter since the average of a single value is the value itself.

To access digital filter settings, select Filters from the menu. The display appears as follows:

Two filters are available:

Current Reading – Applies to the peak capture rate of the instrument.

Displayed Reading – Applies to the primary reading on the display.

Available settings: 1,2,4,8,16,32,64,128,256,512,1024. It is recommended to keep the current reading

filter at its lowest value for best performance, and the displayed reading filter at its highest value for best

stability.

8 SET POINTS

8.1 General Information

Set points are useful for tolerance checking (pass/fail) and triggering an external device in process control

applications. Two limits, high and low, are programmed in the tester, and the primary reading is compared

to these limits. The results of the comparisons are indicated via on-screen indicators as well as through

the three outputs provided on the 15-pin connector, thus providing “under”, “in range”, and “over”

signaling. These outputs can be connected to indicators, buzzers, or relays as required for the

application. On-screen indicators are described in the next sub-section.

8.2 Configuration

To configure set points, select Set Points from the menu. The display appears as follows:

The TT05 should be mounted to a fixture rugged enough to withstand a load equal to the full capacity of

the tester. Suitable certified calibration equipment is required, and caution should be taken while handling

such equipment.

13.2 Calibration Procedure

1. Select Calibration from the menu. The display appears as follows:

2. Press DIRECTION to invert the display, if desired. ENTER to continue. The display appears as

follows:

The tester can be calibrated at up to 10 points in each direction. Enter the number of calibration

points for each direction (clockwise and counter-clockwise). At least one point must be selected

for each direction.

Note: To achieve the accuracy specification of ±0.3%, it is recommended to calibrate the tester at

5 or more even increments in both directions. For example, an MTT05-50 should be calibrated at

10, 20, 30, 40, and 50 lbFin loads in each direction.

3. To escape the Calibration menu at any time, press ESCAPE. The display appears as follows:

Selecting “Cancel” will revert back to the Calibration setup. Selecting “Exit w/o saving” will return

to the menu without saving changes.

4. After the number of calibration points has been entered, press ENTER. The display appears as

follows:

5. Place the tester on a level surface free from vibration, then press ZERO. The tester will calculate

internal offsets, and the display appears as follows:

If failed:

6. The following screen appears after the offsets have been calculated:

Attach weight fixtures (brackets, hooks, etc), as required. Do not yet attach any weights or apply

any calibration loads. Press ENTER.

7. The display appears as follows:

Optionally exercise the torque sensor several times (at full scale, if possible), then press ENTER.

Apply a weight equal to the full scale of the instrument, then press ENTER.

9. After displaying “Please wait…” the display appears as follows:

Remove the load applied in Step 8, leave the fixtures in place, then press ZERO.

10. The display appears as follows:

Use the UP and DOWN keys to adjust the load value as required. The load values default to even

increments, as indicated by the previously entered number of data points (even increments are

recommended for best results). For example, if a 50 lbFin capacity tester is calibrated, and 5 data

points were selected, the load values will default to 10, 20, 30, 40, and 50 lbFin. Apply the

calibration load. Then press ENTER.

Repeat the above step for the number of data points selected.

11. After all the clockwise calibration points have been completed, the display appears as follows:

Press ENTER.

12. Attach weight fixtures. The following screens will step through the same procedure as with the

compression direction. Proceed in the same manner.
